MACHINE FOR MAKING SUPPOSITORIES.

SPECIFICATION forming part of' Letters Patent No. 244,030, dated July 12, 1881,

I Application filed May 16, 1881. (No model.)

To all whomjt may concern:

Be it known that I, EDWARD WILLIAM BING, a subject of Great Britain, residing in the city and county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Improvement in Machines for Making Suppositories, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a perspective view of the machine embodying my invention. Figs. 2 and 3 are plan views of detachable trays thereof. Fig. 4 is a plan view with the trays in position. Fig. 5 is a transverse vertical section in line as at, Fig. 1, the trays being added.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a machine for making suppositories whichis simple, inexpensive, and durable, and operates quickly, reliably, and uniformly, as will be hereinafter fully set forth.

Referring to the drawings, A represents the bed-plate of the machine, the upper face of which is depressed or grooved longitudinally, the base of the groove being somewhat inclined, as at a, and curved or bent upwardly, as at b.

B represents the roller plate or slide, which is formed with longitudinally-extending depending flanges c, which, when said plate is fitted on the bed-plate, overlap the side walls (I d of the latter, and serve to guide the rollerplate and retain it in position.

It will be noticed that the wall (I of the bedplate is higher than the wall cl. Consequently the inner face of the roller-plate is inclined in the direction the reverse of the inclined portion a. of the base, thus forming a tapering space between the bed-plate and roller-plate, as shown in Figs. land 5.

The mass from which the suppository is to be formed is properly divided, and one or more of the parts placed on the bed-plate A, in the groove thereof, properly dusted. The rollerplate B is now located over the bed-plate and moved to and fro with a gradually-increasing pressure until the suppository is properly shaped, after which it is removed.

In order to produce suppositories of smaller size I employ a tray, (3, and for a smaller size a tray, D, and may employ still smaller ones, if desired. The trays O D have each hooks or hooked ends 0 e, which are adapted to engage with the wall d of the bed-plate, as more clearly shown in Fig. 4:. The tray O is placed in the groove of the bed-plate and reduces the space between the latter and the roller-plate, and the tray D is placed on the tray 0, thus further reducing said space, whereby it is evident that smaller masses must be employed and smaller suppositories will be produced, it being noticed that the contour of the upper faces of the trays O D accords with the upper face of the bed-plate, the only variation being in the size, as has been stated.

The trays, owing to their hooks or hooked ends 0, may be readily located and reliably re:

tain their position, especially during the manipulations or movements of the roller-plate B.

The device or machine will be found to be strong and durable and render efficient service, all molds and complicated and expensive parts being dispensed with, and freezing of the suppository while setting it avoided.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The bed-plate and roller-plate having their inner faces form a tapering space between them, substantially as and for the purpose set forth.

2. The bed-plate provided with removable trays O D, substantially as and for the purpose set forth.

3. The suppository-machine provided with removable trays, which are formed with hooks adapted to engage with the bedplate, substantially as and for the purpose set forth.

- EDWARD WM. BING.
